Hluav Taws Xob Qhov Cub Hlau Hluav Taws Xob Qhov Cub Hlau Hluav Taws Xob Kev Lag Luam Hluav Taws Xob Rauv Hlau Kub Tiv Thaiv

Cov Ntaub Ntawv Dav Dav

Hlau Hluav Taws Xob Rau Qhov Cub yog ib hom hlau hluav taws xob uas tiv taus hluav taws xob heev. Cov hlau no tiv taus hluav taws xob, thiab hloov lub zog hluav taws xob mus ua cua sov.

Daim ntawv thov rau cov hlau tsis kam suav nrog cov resistors, cov khoom cua sov, cov cua sov hluav taws xob, cov qhov cub hluav taws xob, cov toasters, thiab ntau ntxiv.

Nichrome, ib qho hlau tsis muaj hlau nplaum ntawm nickel thiab chromium, feem ntau siv los ua hlau tiv taus vim nws muaj qhov tiv taus siab thiab tiv taus oxidation ntawm qhov kub siab. Thaum siv ua lub cua sov, hlau tiv taus feem ntau yog qhwv rau hauv cov kauj. Ib qho nyuaj hauv kev siv Hluav Taws Xob Qhov Cub Hlau yog tias cov khoom siv hluav taws xob feem ntau yuav tsis lo rau nws, yog li kev sib txuas rau lub zog hluav taws xob yuav tsum tau ua los ntawm kev siv lwm txoj hauv kev xws li crimp connectors lossis ntsia hlau terminals.

FeCrAl, ib tsev neeg ntawm cov hlau-chromium-aluminium alloys siv rau hauv ntau yam kev tiv thaiv thiab kev siv kub siab kuj tseem siv rau hauv daim ntawv ntawm cov xov hlau tiv thaiv.
